We describe a subfringe integration interferometry for which the phase information is evaluated only from one interferogram.

叙述了次积分干涉计量的原理，仅用一幅光载频干涉获全信息。

The conoscopic interference patterns of crystals are calculated for any orientation biaxial crystal, which include information of isochromatic curve and isogyre.

针对任意向的双轴晶体,计算了完整的偏光干涉,反映了分布决定等色线、振幅分布决定消光影的规律。
